Glass nails are one of the most common accessories you will receive when you purchase your dab rig. You will find that dabbing with a glass nail will offer you a much cleaner hit in comparison to using another material. Glass nails are also great if you are not looking to make an expensive purchase and just want a simple replacement nail. HerbTools also offer domeless nails
which you can use on any bong with the correct joint size to transform it into a dab rig.
